Description
Up to 7 PBXs connected with this PBX in a TIE line network over VoIP or ISDN can share the services of the
Unified Messaging system of this PBX. The Unified Messaging system can provide voice mail for extensions

using the Message Waiting Button.
The Unified Messaging features available at extensions in a network are as follows:
• FWD to a Mailbox
• Intercept Routing to a Mailbox
• Voice Mail (VM) Transfer Button
• Listening to a Recorded Message (Direct Mailbox Access)
• Trunk Service & Automatic Time Mode Notification for Incoming Call

[Explanation]
A
trunk call is answered by the AA service of the Unified Messaging system. The caller enters extension number
201, so the call is transferred over the private network to extension 201.
If extension 201 does not answer, mailbox 201 will answer it and play the appropriate message.
